To LZ2 whom, it may concern:

Be it known that I, CHARLES S. HUNTINd TON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, haveinvented a new and useful Door-Lock, of which the following is a specification.

The invention relates to improvements in door-locks.

The object of the present invention is to improve the construction of door-locks and to provide a simple and comparatively inexpensive one adapted to serve as a latch and capable of being locked and unlocked from the in,- r5 terior by the inner knob and of being locked from the exterior by the outer knob, so that a key will be required to unlock it from the exterior.

zo vide a lock of this characterV Which when locked by the inner knob will eifectually prevent the introduction of a key fromthe eX- terior.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

l designates a lock-casing, which when the lock is designed for use as a rim -lock is provided with a removable faceplate 2, but whichlnay be constructed for use as a mortise-lock, as illustrated in Figs. 2 and 3 of the accompanyingV drawings. The lock may be made eitherl right or left hand, and the back or body of the casing is provided with a lower side 3 and a rear side or ilange 4. The removable faceplate 2 is provided with a top side 5, a front side 6, and a rear side or flange 7, which completes the back of the casing. TherearsideorflangeVisprovidedwith an extension 8, and the top side 5 is provided near the frontend of the casing With asimilar extension 9. These extensions 8 and 9 are perforated for the reception of screws or other Vsuitable fastening devices for securing the lock to the door. The front side 6 is extended and is adapted to be arranged on the front edge of the door and is perforatedfor the reception of a suitable fastening device for securing itto the same. The back of the casing is provided` with* a post 10, having a threaded socket for the reception of a screw or other suitable fastening device for securing theface-plate to the back of the casing. The'lock-casing, which may be constructed in any other suitable manner, is provided at its front with an opening 11 for the reception of the outer end of a bolt l2, having a limited reciprocation to enable it to serve the purposes of a latch and capable of being eX- tended to operate as a locking-bolt.

The bolt, which has its body portion located between the post l0 and the top of the casing, hasits front portion enlarged'and is provided thereat with a depending arm 13, and it has a beveled nose 14, adapted to engage a keeper l5, whereby when the doorl is closed the bolt,

Vwhich is spring-actuated, is reciprocated or moved inward and is causedto'engagethe keeper automatically, the spring ythrowing the bolt outwardV into engagement with the keeper after the noselc has passed the front of the said keeper. The keeper may be constructed in any suitable manner and is provided at its front with a curved flange or eX- tension 16, forming a curved loop and arranged to be engaged by the end of the bolt.

IOO

One end of the loop is formed integral with the keeper, and the other end is suitably secured to the same, preferably by means of a tongue, as indicated in Fig. 11 of the drawings. The arm 13, which depends from the front of the bolt, is adapted to be engaged by a key 17 to unlock the door from the exterior thereof. The arm 13, which is arranged vertically, is provided at its front edge with an inwardly-extending horizontally-disposed lu g 18, arranged to be engaged by the front or outer end of a catch or tumbler 19.

The bolt is provided at its inner end with recesses 2O and 21, forming inner rear shoulders adapted to be engaged by inner and outer hubs or sleeves 22 and 23, mounted on a transverse spindle 24 and connected by the means hereinafter described with inner and outer knobs 25 and 26 and adapted to be operated by the same. The outer hub or sleeve 23 is provided with four diametrically-arranged arms or lugs 27, having rounded outer ends and adapted to engage either the inner end of the bolt or the shoulder formed by the outer recess 21 of the said inner end of the bolt. When the outer knob is rotated backward, one of the lugs is carried into engagement with the shoulder formed by the recess 2l, and the bolt is moved inward against the action ofthe spring 28 to disengage it from the keeper. When the outer knob is rotated forwardly, one of the lugs or arms 27 is carried into engagement with the rear end of the bolt, which is thrown forward beyond the reach of the lugs or arms 27, so that after such operation the bolt cannot be retracted by operating the outer knob.

The lug or projection 18 of the depending arm 13 is located beneath the outer arm or portion 29 of the catch or tumbler, which is provided at its outer end with a bend forming an inclined portion 30 and a vertical por` tion 31. The inclined portion presents an inclined lower face to the arm or lug 18, and when the bolt is moved outward by the outer knob the lug or arm 18 moves outward and lifts the outer armor portion of the catch or tumbler and passes beyond the vertical portion 31, which drops behind the said lug or projection 18 and locks the bolt against inward movement. The front arm or portion of the catch or tumbler is held in engagement with the lug or projection 18 by the spring 28.

TheV catch or tumbler 19 is provided between it-s ends with a perforated ear and is pivoted to the back of the casing by a rivet 32 or other suitable fastening device. The rear arm 'or portion 33 of the catch or tumbler is angularly bent and laterally offset from the plane of the perforated ear, and it is provided with openings 34 and 35. The spring 28, which is disposed longitudinally of the casing, has its inner or rear end supported by a ange or projection 36, and it extends upward through the opening 34 and engages the rear 'arm or portion of the catch or tumbler at the top of the opening, whereby the outer or front arm or portion 29 is thrown downward and is held inengagement with the lug or projection 18 of the bolt.

The inner hub or sleeve 22 is provided with front and rear upper arms or lugs 37 and 38, arranged to engage the bolt, as clearly shown in Fig. 1. The arm or lug 38 is adapted to engage the rear end of the bolt to throw the same forward to lock the door from the interior by rotating the inner knob, and the arm orlug 37,which is adapted to engage the shoulder formed by the recess 2O to move the latchbolt inward, is enlarged or extended and is of greater length than the lugs or arms 27 of the outer sleeve or hub in order to enable the bolt to be unlocked from the interior by rotating the inner knob backward. The inner hub or sleeve is also provided with a depending arm 39, arranged to engage the rear arm or portion of the tumbler or catch to lift the front or outer arm of the same out of engagement with the laterally-extending lug or projection of the bolt to release the latter to permit the said bolt to be moved inward by the arm or lug of the inner hub or sleeve.

The depending arm or lug 39 is provided witha recess 40, forming a shoulder to engage the .upper edge of the pivoted tumbler or catch and providing an extension which is adapted to engage and reciprocate a sliding guard 41. The rear portion or arm of 'the tumbler or catch is provided with a lateral projection or lug 42, extending beneath the fiange or support 36 and limiting the upward movement of the said inner arm or portion of the tumbler to prevent the same from be ing displaced by the action of the spring 28.

The sliding keyhole-guard, which is provided with a solid front portion or block 43, has a recess 44 at its rear portion, forming opposite shoulders to be engaged by the depending lug or arm of the sleeve or hub 22. When the depending arm of the inner hub or sleeve swings rearward, it engages the rear shoulder or wall formed by the recess 44, and when it is moved forward it engages the front Wall of the same. The solid portion or block 43 at the front end of the sliding guard is adapted tobe carried by such inward movement to a point directly opposite the keyhole 45, whereby when the door is locked from the interior by rotating the inner knob it will be impossible to introduce a key or instrument into the lock from the exterior. The sliding keyhole-guard is locked against movement by means of an L-shaped arm or lug 46, extending upward and laterally from the inner or rear portion of the guard and adapted to be carried in advance and in rear of a projection or lug 47, extending upward from the bottom of the opening 35 of the rear poi-tion of the catch or tumbler. The rear portion of the catch or tumbler is depressed, while the projection or lug of the sliding keyholeguard is reciprocated backward and forward.

The key which is employed for unlocking the door from the exterior after the same has IOO IIO

been locked by the knob 26 is provided with a tubular portion or barrel 48, which is adapted to fit over a rounded stud 49, carried by the sliding keyhole-guard and located opposite the keyhole when the said guard is at the limit of its outward movement. The guard is provided with projections 50, 51, and 52, arranged as clearly illustrated in Fig. 13 of the accompanying drawings. The keyis notched, as shown in Fig. 14, to correspond to the projections 50, 51, and 52, and these may be arranged in a variety of different positions to change the character of the key, as will be readily apparent. When it is desired to unlock the door from the exterior, the key is inserted in the lock and when turned engages and lifts the front or outer portion of the catch or tumbler and reeiprocates the bolt by engaging the depending arm 13. This movement carries the bolt rearward sufciently to bring the rear end of the same within reach of the arms or lugs 27 of the outer hub or sleeve, which is then partially rotated by the outer knob to complete the unlocking operation. The front portion of the spring 2S extends upward beyond the front arm or portion of the tumbler or catch and engages a shoulder 53, formed by the enlarged front portion of the bolt. The enlarged front portion of the bolt lying in rear of the beveled nose is carried outward into engagement with the keeper by the locking operation.

The outer knob is provided with a shank having portions 54 and 55, the outer portion 55, or that portion lying farther from the inner face of the knob 26, being of less diameter than the inner portion 54 and extending well into the door to conceal the screw 56 to prevent the outer knob from being removed from the exterior' after the parts have been assembled. The inner portion 54is provided with a pair of oppositely-disposed ribs 57, forming shoulders adapted to be engaged by a latch 58, which is pivotally mounted on an outer door-plate or escutcheon 59, which is suitably secured to the door. The outer doorplate or escutcheon is provided with a keyhole 60, and it preferably has a flange 61 at its outer end, and this iiange 61 is designed to be arranged at the outer or free edge of the door and may be provided with a spur or projection, as indicated in Fig. 12. The inner portion of the plate 59 is provided with an opening to receive the shank of the knob, and the latch, which is located above the opening and beneath a stop 59, is pivoted at its inner or lower end 62, and its outer or free portion, which is adapted to rest upon the shank of the outer knob, is provided with a shoulder 63 for engaging the ribs 57. The latch prevents the outer knob from being turned forwardly suiciently to lock the door. The outer knob, when the latch is in engagement with it, is adapted to be partially rotated to impart to the bolt a limited reciprocation to engage its beveled nose with the keeper and to disengage it therefrom, and the spring will operate to throwT the bolt outward. When it is desired to lock the door from the exterior, the latch is raised and the outer knob is turned forwardly to carry one of the lugs or arms 27 into engagement with the rear end of the bolt. This throws the bolt forward or outward, as before explained.

The shank of the outer knob is r provided with a circular bore or opening to receive the spindle 24, and the inner knob, which is provided with a shank 64, has a rectangular opening to receive the inner end of the spindle, which is provided with exterior screw-threads 65 and which has an interiorly threaded socket 66. The knob 25 is provided at its outer face with a socket to receive a cylindrical nut 67, which engages the exterior screw-thread 65 and which is engaged by the thread of a screw 68. The screw 68 engages the interior screw-threads of the socket of the inner end of the spindle and retains the nut in place. One set of screw-threads is designed to be right-hand and the other left-hand, so that the nut and the screw will operate as alock.

` The outer portion of the shank 64 of the inner knob is provided with a rectangular opening for the reception of a rectangular sleeve 69, which is adjustably secured to the knob and which iits within a rectangular opening 70 of the inner hub or sleeve, whereby the latter is interlocked with the inner knob and is adapted to be rotated by the same. The rectangular sleeve is provided with apertures 7l, adapted to be engaged by a screw 72 to permit the parts to be adjusted to suit the thickness of a door, and the screw 56 is also adapted. to permit the parts to be adjusted for that purpose. The inner knob is arranged on a cylindrical sleeve or barrel 73, extending entirely through the inner knob to the nut and interposed between the latter and the outer hub or sleeve and provided adjacent to the same with a recess 74. The recess 74, which is formed by cutting away the inner end of the cylindrical sleeve or barrel, receives a curved flange 7S of a bracket 79. The curved flange 78, which extends laterally from the bracket 79, completes the inner end of the cylinder or barrel 73, and the bracket '79,wl1ich is secured to the rear wall of the lock-casing, is interposed between the inner and outer hubs or sleeves. The rear end of the bracket is provided with a liange, which is perforated for the reception of suitable fastening devices for securing the bracket to the lock-casing.

It will be seen that the lock is simple and comparatively inexpensive in construction, that it is adapted to be locked and'unlocked from the interior by the inner knob and from the exterior1 by the outer knob and a key, and that when locked from the interior by the inner knob the keyhole is automatically closedA by the guard to prevent a key or instrument from being introduced into the lock from the exterior. Also it will be seen that the lock cannot be unlocked from the exterior by the IOO IIO

outer knob, and that the pivoted latch limits the forward movement of the outer knob to prevent the lock from being accidentally locked by the outer knob, and that the knobs are independently movable and 'do not affect the rotation of each other.

The sliding spring-actuated bolt has a limited reciprocation to serve as a latch and an extended reciprocation to operate as a locking-bolt, and the catch or tumbler permits a free reciprocation of the bolt when the latter operates as a latch and is lcapable of locking the bolt in its extended position.
